重点语法

基数词的构成及用法构成:

1.1-12的表述1-12各有各的形式,即one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve。

2.13-19的表述13-19的数字皆以-teen[ti:n]结尾,其中,fourteen,sixteen,seventeen,eighteen和nineteen分别由four,six,seven,eight,nine加后缀-teen变成的,eighteen中只保留一个t。thirteen,fifteen分别由three和five转花而来。

3.20-90数字的表达20-90的数字皆以-ty结尾,其中,sixty,seventy,eighty,ninety分别由six,seven,eight和nine加后缀—ty构成,eighty中只保留一个t。其他同上。

4.20-99之间的数字的表达20-99之间的数词须在十位和个位之间加连字符“-”,如twenty-five。

5.百位以上的数字的表达以及读在表达百位以上的数字时,必须在百位,十位和个位之间加and,在读音时也应读上and,如:104可表达为one hundred and four,486读作four hundred and eighty-six。

6.“万”的表达.英语中没有万和亿单词,只有百(hundred),千(thousand),百万(million),十亿(billion)。英语中表示“万”时,用10千。如:forty  thousand四万。表示“亿”时需用百万来表示。如:two hundred million两亿。

7.1,000以上的数字,从后向前数。每三位数加“,”。第一个“,”前为thousand,第二个“,”前为million,第三个“,”前为billion.3,333,333,333读为three  billion,three  hundred  and thirty-three  million, three  hundred  and thirty-three thousand,three  hundred  and thirty

8.hundred,thousand,million 前有若有具体数字时,要用单数形式,但如果他们后面有of ,则要用复数形式。同时,前面不能再加具体的数目。

序数词的构成及用法

1 第一,第二,第三分别为first,second,third.

2 第四到第十九都有相应的基数词加th构成,有几个特殊,即fifth,eighth,ninth,twelfth.

3 第几十把y改为 i加eth..  twentieth,ninetieth

4 序数词之前要加定冠词或代词。但序数词表名词时,可不用冠词。Who won first?

序数词表“再一”,“又一”时不用定冠词,只需在前面加a

He failed once .Then he tried a second time.

5序数词的缩写形式是在数字后面直接加上序数词最后两个字母构成。1st,2nd,3rd,4th,21st,22nd,34th……

6 100以上的序数词的表示方法 第100为100th (读作 one  hundredth),101st 读作one  hundred  and  first,其他的依次类推

分数的表示法

1 分数的表示法:分子用基数词,分母用序数词,当分子大与一时,分母用复数形式。

2|3  two  thirds  3|5  three  fifths

2 整数与分数之间用and 连接。 One /an  hour and a half

3 分数的用法结构为“分数+of+the+名词”表示“。。。。的几分之几”,当其作主语时,谓语动词的单复数取决于短语中名词的复数

One third of the shop assisstant in this departmentstore      men

年月日的表达法

2004年11月25 日:November 25(th),2004(thNovemb读作November  (the) twenty-fifth,two thousand and  four.
